Description
技术领域 technical field
本发明涉及室内通风空调技术领域，具体涉及一种毛细管网辐射换热吊顶板及其吊顶铺装结构。 The invention relates to the technical field of indoor ventilation and air conditioning, in particular to a capillary network radiation heat exchange ceiling board and a ceiling pavement structure thereof.
背景技术 Background technique
自20世纪70年代德国科学家根据仿生学原理发明毛细管辐射式空调系统以来，虽然多数时间内其备受冷落，但是随着全球能源成本越来越高，环境污染和温室效应加剧，各国政府都在提高节能减排的标准，使得毛细管辐射采暖制冷技术成为近年来业界研发热点。 Since German scientists invented the capillary radiant air-conditioning system based on the principle of bionics in the 1970s, although it has been neglected for most of the time, as the global energy cost is getting higher and higher, environmental pollution and the greenhouse effect are intensifying, governments of all countries are working on it. Improving the standards for energy saving and emission reduction has made capillary radiant heating and cooling technology a hot spot in research and development in the industry in recent years.
辐射吊顶板就是一种利用毛细管辐射采暖制冷技术的空调末端产品，其主要通过在导热材料板上铺设毛细管网，由毛细管网内流动的换热介质通过导热材料板与室内空间进行热辐射和对流换热，实现供冷或供热，因此减小了空气分层，具有室内温度分布均匀，换热能量利用率高，无吹风感，噪音低，舒适度好等特点，并且其换热介质还可以采用可再生能源（例如太阳能，以及土壤、地下水、空气、污水、地表水、发电厂废水等蕴含的能量）作为换热能来源，有利于节能减排、环保和提升建筑物空调能效品质。国内外大量项目应用表明，辐射吊顶板技术是建筑物较为理想的空调末端系统。 The radiant ceiling panel is an air-conditioning terminal product that uses capillary radiation heating and cooling technology. It mainly lays a capillary network on a heat-conducting material plate, and the heat exchange medium flowing in the capillary network conducts heat radiation and convection with the indoor space through the heat-conducting material plate. Heat exchange to realize cooling or heating, thus reducing air stratification, with uniform indoor temperature distribution, high utilization rate of heat exchange energy, no blowing sensation, low noise, good comfort, etc., and its heat exchange medium is also Renewable energy (such as solar energy, and the energy contained in soil, groundwater, air, sewage, surface water, power plant wastewater, etc.) can be used as the source of heat exchange energy, which is conducive to energy saving, emission reduction, environmental protection and improving the energy efficiency of building air conditioning. The application of a large number of projects at home and abroad shows that the radiant ceiling technology is an ideal air-conditioning terminal system for buildings.
通过目前技术实现的辐射吊顶板虽然优势突出，但也有其自身的局限性。在冬季，由于受到辐射吊顶板中毛细管网与导热材料板之间导热效率的限制，加热温度也不宜过高，一般为25~35℃，否则过高温度的换热介质其热能难以有效通过导热材料板向外辐射，从而导致大量热能在辐射板内聚集，容易加速内部器件老化，缩短使用寿命，且舒适度降低而能耗增加；而在夏季，不仅因导热效率的限制影响了辐射吊顶板的根供冷性能，同时其制冷温度也不宜过低，一般为18~20℃，过低的制冷温度会使得辐射吊顶板产生结露聚集而滴落到室内，影响室内卫生条件，这就进一步限制了辐射吊顶板在单位面积上的制冷换热能力。因此，供暖、供冷能力不足的因素，使得辐射吊顶板技术难以满足具有较大供暖、供冷负荷的需求，从而大幅限制了辐射板系统在更多地区和领域的推广应用。 Although the radiant ceiling panels realized by the current technology have outstanding advantages, they also have their own limitations. In winter, due to the limitation of the heat conduction efficiency between the capillary network in the radiant ceiling and the heat conduction material plate, the heating temperature should not be too high, generally 25~35°C, otherwise the heat energy of the heat exchange medium with too high temperature will not be able to effectively pass through the heat conduction The material board radiates outwards, which causes a large amount of heat energy to accumulate in the radiant board, which easily accelerates the aging of internal devices, shortens the service life, and reduces comfort and increases energy consumption; in summer, not only the limitation of heat conduction efficiency affects the radiant ceiling board At the same time, the cooling temperature should not be too low, generally 18~20°C. If the cooling temperature is too low, condensation will accumulate on the radiant ceiling and drip into the room, which will affect the indoor hygienic conditions. The cooling and heat transfer capacity of the radiant ceiling board per unit area is limited. Therefore, the lack of heating and cooling capacity makes it difficult for radiant ceiling panel technology to meet the needs of large heating and cooling loads, which greatly limits the promotion and application of radiant panel systems in more regions and fields.

In the capillary network radiation heat exchange ceiling panel of the present invention, the grooves on the heat-conducting material plate can be formed by stamping, which not only makes the forming process of the heat-conducting material plate relatively simple, but also forms grooves on the surface of the heat-conducting material plate after stamping At the position of the downwardly recessed groove, downward convex ribs are correspondingly formed on the lower surface of the thermally conductive material plate, thereby increasing the heat exchange contact area on the lower surface of the thermally conductive material plate, and the heat radiation rays at the lower convex ribs It presents a local divergent radiation state, so that the heat-conducting material plate also has a better external heat exchange effect; at the same time, the lower convex ribs on the lower surface of the heat-conducting material plate also help to scatter the spatial noise in different directions to reduce the indoor environment. The effect of noise pollution.
3、本发明的毛细管网辐射换热吊顶板中，在毛细导热管凸出于所述沟槽部分的管壁位置处以及导热材料板朝向中空腔室的一面上位于沟槽之间的间隔位置处均紧贴敷设了反射膜，通过反射膜，不仅形成了对毛细换热管所散发热量/冷量的向下反射，同时还隔绝了毛细换热管与沟槽之间的间隙位置处与上部空间的连通，从而尽可能的减少毛细换热管热量/冷量的向上散失。 3. In the capillary network radiation heat exchange ceiling plate of the present invention, the capillary heat pipe protrudes from the wall position of the groove part and the space between the grooves on the side of the heat conducting material plate facing the hollow chamber The reflective film is laid close to each other. Through the reflective film, it not only forms a downward reflection of the heat/cold emitted by the capillary heat exchange tube, but also isolates the gap between the capillary heat exchange tube and the groove from the The communication of the upper space, so as to reduce the upward loss of heat/cooling capacity of the capillary heat exchange tube as much as possible.
4、本发明的毛细管网辐射换热吊顶板中，由于吊顶板壳体对毛细换热管的包围形成了相对闭合的封装空间，且在反射膜的上方与吊顶板壳体顶面板之间的间隙空间内还填充了保温隔热材料，因此毛细换热管通过反射膜的热传递而向上传导的少量热量/冷量也被封闭在吊顶板壳体内所填充的保温隔热材料中，进一步减少了热量/冷量的向上散失，不仅如此，反射膜的上方与吊顶板壳体顶面板之间所填充的保温隔热材料除了起到隔热作用之外，还同时形成了对反射膜和毛细换热管的向下挤压，使得毛细换热管与导热材料板上沟槽的槽壁更加紧密的贴合接触，进一步保证了毛细管换热管与导热材料板之间良好的接触传热性能。 4. In the capillary network radiation heat exchange ceiling panel of the present invention, since the ceiling panel shell surrounds the capillary heat exchange tubes, a relatively closed packaging space is formed, and the space between the top of the reflective film and the top panel of the ceiling panel shell The gap space is also filled with thermal insulation material, so the small amount of heat/cold conducted upward by the capillary heat exchange tube through the heat transfer of the reflective film is also enclosed in the thermal insulation material filled in the ceiling panel shell, further reducing Not only that, the thermal insulation material filled between the top of the reflective film and the top panel of the ceiling panel shell not only plays a role of heat insulation, but also forms a barrier to the reflective film and capillary at the same time. The downward extrusion of the heat exchange tube makes the capillary heat exchange tube more tightly contact with the groove wall of the groove on the heat conduction material plate, further ensuring the good contact heat transfer performance between the capillary heat exchange tube and the heat conduction material plate .
5、本发明的毛细管网辐射换热吊顶板采用了模块化的结构，可以直接用于吊顶铺装形成多种形式的吊顶铺装结构，安装方便，且排布形式灵活多样，可以应用于不同的建筑场景中。 5.

具体实施方式 detailed description
现有技术中，辐射吊顶板中毛细管网与导热材料板之间导热效率较为有限，是影响其换热能效的一个重要因素；通过技术分析发现，造成其导热效率受限的主要原因在于，由于毛细管通常是横截面为圆形的管道（因为圆形截面毛细管道的制造工艺较为成熟，制造成本相对较低），而现有技术的辐射吊顶板中，与毛细管网相配合的导热材料板通常为平板，导热材料板与毛细管的直接接触仅为线接触，接触传热性能较差，更多的依靠毛细管向周边热辐射后将热量传导至导热材料板，不仅增加了毛细管与导热材料板之间热传导过程中热量/冷量的消耗，而且在供暖时也增加了毛细管向外传导的热能在辐射板内聚集，从而更易引发内部器件老化、使用寿命缩短的问题。 In the prior art, the heat conduction efficiency between the capillary network and the heat conduction material plate in the radiant ceiling plate is relatively limited, which is an important factor affecting its heat exchange energy efficiency; through technical analysis, it is found that the main reason for the limited heat conduction efficiency is that due to The capillary is usually a pipe with a circular cross-section (because the manufacturing process of the circular-section capillary is relatively mature, and the manufacturing cost is relatively low), while in the radiant ceiling panels of the prior art, the heat-conducting material plate matched with the capillary network is usually It is a flat plate, and the direct contact between the heat-conducting material plate and the capillary is only linear contact, and the contact heat transfer performance is poor. It relies more on the capillary to radiate heat to the surroundings and then transfers the heat to the heat-conducting material plate, which not only increases the distance between the capillary and the heat-conducting material plate. The consumption of heat/cold energy during the heat conduction process, and the heat energy conducted by the capillary to the outside is also increased in the heating process to accumulate in the radiant plate, which is more likely to cause the aging of internal components and shorten the service life.
针对于此，本发明提供了一种毛细管网辐射换热吊顶板，通过结构的改进而提升其换热能效。图1示出了本发明毛细管网辐射换热吊顶板一种具体实施结构的俯视透视图；图2示出了图1所示毛细管网辐射换热吊顶板的A-A剖视图；图3示出了图1所示毛细管网辐射换热吊顶板中毛细导热管在导热材料板上的贴设结构局部放大图；图4示出了图1所示毛细管网辐射换热吊顶板的B-B剖视图。如图1~4所示，本发明的毛细管网辐射换热吊顶板包括整体呈扁平的长方体状且具有中空腔室的吊顶板壳体100，吊顶板壳体100的底面板为导热材料板101；所述中空腔室内位于导热材料板101上并行排列地分布贴设有若干用于供换热介质流动的毛细导热管102，且导热材料板101上与毛细导热管102相接触位置处形成向下凹陷且与毛细导热管的下侧管壁形状相匹配的沟槽103，使得毛细导热管102的下侧管壁陷入所述沟槽103中且与沟槽103的槽壁相贴合接触，所述毛细导热管102凸出于所述沟槽部分的管壁位置处以及导热材料板101朝向中空腔室的一面上位于沟槽之间的间隔位置处均紧贴敷设有反射膜104，且反射膜104的上方与吊顶板壳体顶面板之间的间隙空间内填充有保温隔热材料105；吊顶板壳体100的中空腔室内还沿侧壁横向设置有供水导流管106和回水导流管107，导热材料板101上各毛细导热管102的两端分别与所述供水导流管106和回水导流管107相连通，供水导流管106的一端和回水导流管107的一端分别从吊顶板壳体同侧的侧面板或两个相对的侧面板穿出，且分别在相应侧面板上形成用于连接供水管道的供水接口108和用于连接回水管道的回水接口109；所述吊顶板壳体100上相邻于供水接口108所在侧面板的两个相对的侧面板上的对应位置处还设置有能够相互匹配连接的连接结构110。 Aiming at this, the present invention provides a capillary network radiative heat exchange ceiling plate, the heat exchange energy efficiency of which is improved through structural improvement. Fig. 1 shows a top perspective view of a specific implementation structure of the capillary network radiation heat exchange ceiling panel of the present invention; Fig. 2 shows the A-A sectional view of the capillary network radiation heat exchange ceiling panel shown in Fig. 1; Fig. 3 shows the diagram Figure 1 shows a partial enlarged view of the capillary heat transfer tube on the thermally conductive material plate in the capillary network radiation heat exchange ceiling plate; Figure 4 shows the B-B sectional view of the capillary network radiation heat exchange ceiling plate shown in Figure 1. As shown in Figures 1 to 4, the capillary network radiation heat exchange ceiling panel of the present invention includes a ceiling panel shell 100 that is flat as a cuboid and has a hollow chamber as a whole, and the bottom panel of the ceiling panel shell 100 is a heat-conducting material plate 101 In the hollow chamber, a plurality of capillary heat pipes 102 are arranged in parallel on the heat conduction material plate 101 for the flow of the heat exchange medium, and the position where the heat conduction material plate 101 is in contact with the capillary heat pipe 102 forms a direction A groove 103 that is depressed and matches the shape of the lower side wall of the capillary heat pipe, so that the lower side wall of the capillary heat pipe 102 sinks into the groove 103 and is in contact with the groove wall of the groove 103, The capillary heat pipe 102 protrudes from the wall of the groove part and the position of the heat conducting material plate 101 on the side facing the hollow chamber is located at the interval between the grooves, and the reflective film 104 is closely attached to it, and The space above the reflective film 104 and the top panel of the ceiling tile housing is filled with thermal insulation material 105; the hollow chamber of the ceiling tile housing 100 is also provided with a water supply guide pipe 106 and a water return pipe along the side wall. The two ends of the capillary heat pipes 102 on the heat-conducting material plate 101 are connected with the water supply flow pipe 106 and the return water flow pipe 107 respectively, and one end of the water supply flow pipe 106 and the return water flow pipe One end of 107 passes through the side panel on the same side of the ceiling tile shell or two opposite side panels, and the water supply interface 108 for connecting the water supply pipe and the return pipe for connecting the return water pipe are respectively formed on the corresponding side panels. Water interface 109 ; the ceiling panel shell 100 is also provided with connecting structures 110 that can be matched with each other at corresponding positions on the two opposite side panels adjacent to the side panels where the water supply interface 108 is located.
可以看到，在本发明的毛细管网辐射换热吊顶板中，采用了整体呈扁平长方体状的吊顶板壳体形成了对毛细换热管的闭合封装结构，之所以吊顶板壳体设计为扁平长方体状是为了便于模块化吊顶铺装。吊顶板壳体的底面板为导热材料板，作为其辐射换热面，并且与现有技术相比，毛细导热管在导热材料板上的贴设结构方式发生了明显的变化，即导热材料板101上与毛细导热管102相接触位置处形成向下凹陷且与毛细导热管102的下侧管壁形状相匹配的沟槽103，使得毛细导热管102的下侧管壁陷入所述沟槽103中且与沟槽103的槽壁相贴合接触，具体应用时，若毛细换热管的横截面为圆形，则可以设计导热材料板101上沟槽103的槽壁横截面呈与毛细导热管102的下侧管壁相匹配贴合的圆弧形，如图3所示，这样以来，便大幅增加了毛细导热管与导热材料板之间的直接接触传热面积，减少了二者之间热传导过程中热量/冷量的消耗，增强了毛细导热管与导热材料板之间的导热效率，并且毛细换热管陷入沟槽的深度可以达到毛细换热管外径尺寸的40%~50%，以使得在便于将毛细导热管配合安装在导热材料板上的同时，保证毛细导热管与导热材料板之间的直接接触传热面积得以尽可能的增加；当然，若毛细换热管的横截面为其它形状（例如矩形等），则导热材料板上沟槽的槽壁横截面相应采用与毛细导热管的下侧管壁相匹配贴合的形状设计；另一方面，导热材料板上的沟槽可以通过冲压成型，这样以来不仅使得导热材料板101的成型工艺较为简单，而且冲压后在导热材料板101上表面形成沟向下凹陷的沟槽103位置处在导热材料板的下表面相应形成了向下凸起的棱条，如图4所示，从而增加了导热材料板下表面的换热接触面积，并且在下凸棱条处的热辐射射线呈现局部的发散放射状态，使得导热材料板也具备了更好的对外换热效果，同时，导热材料板下表面的下凸棱条也有助于对空间噪声形成不同方向的散射，达到降低室内环境噪声污染的效果；借助上述两方面热传导性能的改善，已足以使得本发明毛细管网辐射换热吊顶板的换热能效得到较大的提升。 It can be seen that in the capillary network radiation heat exchange ceiling panel of the present invention, the ceiling panel shell that is in the shape of a flat cuboid as a whole is used to form a closed packaging structure for the capillary heat exchange tubes. The reason why the ceiling panel shell is designed to be flat The cuboid shape is to facilitate the installation of modular suspended ceilings. The bottom panel of the ceiling panel shell is a heat-conducting material plate as its radiation heat exchange surface, and compared with the prior art, the structure of the capillary heat-conducting tube on the heat-conducting material plate has undergone obvious changes, that is, the heat-conducting material plate A groove 103 that is depressed downward and matches the shape of the lower side wall of the capillary heat pipe 102 is formed at the position where the heat pipe 101 is in contact with the capillary heat pipe 102, so that the lower side wall of the capillary heat pipe 102 sinks into the groove 103 In a specific application, if the cross-section of the capillary heat exchange tube is circular, the cross-section of the groove wall of the groove 103 on the heat-conducting material plate 101 can be designed to be in the same shape as the capillary heat-conducting tube. The lower tube wall of the tube 102 is in a matching circular arc shape, as shown in Figure 3. In this way, the direct contact heat transfer area between the capillary heat conduction tube and the heat conduction material plate is greatly increased, and the distance between the two is reduced. The consumption of heat/cold during the heat conduction process enhances the heat conduction efficiency between the capillary heat transfer tube and the heat conduction material plate, and the depth of the capillary heat transfer tube sinking into the groove can reach 40%~50% of the outer diameter of the capillary heat transfer tube %, so as to facilitate the installation of the capillary heat pipe on the heat-conducting material plate, and at the same time ensure that the direct contact heat transfer area between the capillary heat-conducting tube and the heat-conducting material plate can be increased as much as possible; of course, if the capillary heat-exchanging tube If the cross-section is other shapes (such as rectangle, etc.), the cross-section of the groove wall of the groove on the heat-conducting material plate should be designed in a shape that matches the lower tube wall of the capillary heat-conducting tube; on the other hand, the heat-conducting material plate The groove can be formed by stamping, which not only makes the forming process of the thermally conductive material plate 101 relatively simple, but also forms a groove on the upper surface of the thermally conductive material plate 101 after stamping. Correspondingly, downward convex ribs are formed, as shown in Figure 4, thereby increasing the heat exchange contact area on the lower surface of the heat-conducting material plate, and the heat radiation rays at the lower convex ribs present a local divergent emission state, making the heat conduction The material plate also has a better external heat exchange effect. At the same time, the lower convex ribs on the lower surface of the heat-conducting material plate also help to scatter the spatial noise in different directions, achieving the effect of reducing indoor environmental noise pollution; with the help of the above two aspects The improvement of heat conduction performance is enough to greatly improve the heat exchange energy efficiency of the capillary network radiation heat exchange ceiling plate of the present invention.
而在本发明毛细管网辐射换热吊顶板中，其结构及性能的改进还不仅仅体现在上述两个方面。虽然毛细导热管陷入沟槽部分的下侧管壁与导热材料板直接接触，但毛细导热管凸出于沟槽部分的管壁位置处暴露于导热材料板上方的空间，会造成毛细换热管热量/冷量的向上散失；此外，由于从加工工艺上来讲，不可能保证毛细换热管与导热材料板上的沟槽之间绝对的无缝贴合，在部分区域不可避免的存在未紧密贴合的间隙，而这些间隙空间若与导热材料板和毛细换热管的上部空间相连通，也将导致毛细换热管向下传播的热量/冷量向上方散失。针对于此，如图2和图3所示，在本发明毛细管网辐射换热吊顶板中，在毛细导热管102凸出于所述沟槽103部分的管壁位置处以及导热材料板101朝向中空腔室的一面上位于沟槽之间的间隔位置处均紧贴敷设了反射膜104，通过反射膜，不仅形成了对毛细换热管所散发热量/冷量的向下反射，同时还隔绝了毛细换热管与沟槽之间的间隙位置处与上部空间的连通，从而尽可能的减少毛细换热管热量/冷量的向上散失；此外，由于吊顶板壳体100对毛细换热管102的包围形成了相对闭合的封装空间，且在反射膜104的上方与吊顶板壳体顶面板之间的间隙空间内还填充了保温隔热材料105，因此毛细换热管102通过反射膜的热传递而向上传导的少量热量/冷量也被封闭在吊顶板壳体内所填充的保温隔热材料105中，进一步减少了热量/冷量的向上散失，不仅如此，反射膜104的上方与吊顶板壳体顶面板之间所填充的保温隔热材料105除了起到隔热作用之外，还同时形成了对反射膜和毛细换热管102的向下挤压，使得毛细换热管102与导热材料板上沟槽103的槽壁更加紧密的贴合接触，进一步保证了毛细管换热管102与导热材料板101之间良好的接触传热性能。由此可以看到，在本发明毛细管网辐射换热吊顶板中，相对封闭的吊顶板壳体结合反射膜的采用以及保温隔热材料的填充所起到的反射、隔热及向下挤压作用，使得毛细换热管向外传导的热量/冷量被尽可能的向下传递给导热材料板，减少换热能量散失，提高换热能量利用率，从而进一步的提升本发明毛细管网辐射换热吊顶板的换热能效。 In the capillary network radiation heat exchange ceiling plate of the present invention, the improvement of its structure and performance is not only reflected in the above two aspects. Although the lower tube wall of the capillary heat pipe sinking into the groove is in direct contact with the thermally conductive material plate, the position of the tube wall where the capillary heat pipe protrudes from the groove is exposed to the space above the thermally conductive material plate, which will cause capillary heat transfer tubes The heat/cold is dissipated upwards; in addition, due to the processing technology, it is impossible to ensure the absolute seamless fit between the capillary heat exchange tube and the groove on the heat-conducting material plate, and there is unavoidable non-tightness in some areas. If these gap spaces are connected with the upper space of the thermally conductive material plate and the capillary heat exchange tube, the heat/cold energy transmitted downward by the capillary heat exchange tube will be dissipated upward. In view of this, as shown in FIG. 2 and FIG. 3 , in the capillary network radiation heat exchange ceiling panel of the present invention, at the tube wall position where the capillary heat pipe 102 protrudes from the groove 103 and the heat conduction material plate 101 faces On one side of the hollow chamber, the reflective film 104 is laid close to the space between the grooves. The reflective film not only forms a downward reflection of the heat/cold emitted by the capillary heat exchange tube, but also insulates The gap position between the capillary heat exchange tube and the groove communicates with the upper space, thereby reducing the heat/cold loss upwards of the capillary heat exchange tube as much as possible; The surrounding of 102 forms a relatively closed packaging space, and the gap space between the top of the reflective film 104 and the top panel of the ceiling tile shell is also filled with thermal insulation material 105, so the capillary heat exchange tube 102 passes through the reflective film. A small amount of heat/cold energy conducted upward by heat transfer is also enclosed in the thermal insulation material 105 filled in the ceiling panel shell, which further reduces the upward loss of heat/cold energy. The thermal insulation material 105 filled between the top panels of the plate shell not only plays a role of heat insulation, but also simultaneously forms a downward extrusion on the reflective film and the capillary heat exchange tube 102, so that the capillary heat exchange tube 102 and the capillary heat exchange tube 102 The groove walls of the grooves 103 on the thermally conductive material plate are in closer contact with each other, further ensuring good contact and heat transfer performance between the capillary heat exchange tube 102 and the thermally conductive material plate 101 . It can be seen that, in the capillary network radiation heat exchange ceiling panel of the present invention, the reflection, heat insulation and downward extrusion of the relatively closed ceiling panel shell combined with the adoption of the reflective film and the filling of the thermal insulation material function, so that the heat/cooling capacity conducted outward by the capillary heat exchange tube is transferred downward to the heat-conducting material plate as much as possible, reducing the loss of heat exchange energy and improving the utilization rate of heat exchange energy, thereby further improving the capillary network radiation exchange of the present invention. Heat transfer efficiency of thermal ceiling slabs.
在具体应用时，本发明的毛细管网辐射换热吊顶板中，毛细换热管可以采用直管，也可以采用U型管。在毛细换热管采用直管时，如图5所示，导热材料板101上的各毛细换热管102最好相互并行平行的排列形成一个毛细换热管列队，供水导流管106和回水导流管107则分别位于所述毛细换热管列队的两侧，且与各毛细换热管102相垂直设置，图5中其他标号含义与图1~4相同；而毛细换热管若采用U型管，如图1所示，毛细换热管U型弯折部两侧的两个笔直延伸部最好是相互平行的，而导热材料板上的各毛细换热管最好按照笔直延伸部相互并列平行的形式排列形成一个毛细换热管列队，供水导流管和回水导流管位于所述毛细换热管列队的同侧，且与各毛细换热管的笔直延伸部相垂直设置。这样的毛细换热管、供水导流管和回水导流管的布设方式，可以尽可能的利用吊顶板壳体的内部空间，使得毛细换热管在导热材料板上排布形成覆盖面积较大、各区域换热效果较为均衡的换热覆盖区。本发明毛细管网辐射换热吊顶板中所用的换热介质可以是现有技术的辐射吊顶板技术中常用的换热介质，例如可以是水、制冷剂等。而毛细导热管和导热材料板的具体材料，可以采用现有辐射吊顶板中毛细导热管和导热材料板的制造材料，而作为优选，当使用水作为换热介质时，毛细导热管最好采用聚乙烯塑料管，其在能够满足换热性能需求的同时，有助于降低成本；而当采用制冷剂作为换热介质时，毛细导热管最好采用铜管，以确保毛细导热管具有优良的导热性能和防腐蚀性能。而导热材料板的材质最好采用镀锌钢板，使其除了具备较为优良的导热性能和防腐蚀性能之外，还能够同时兼顾美观性。除此之外，由于导热材料板作为本发明毛细管网辐射换热吊顶板中吊顶板壳体的底面板，考虑到在夏季供冷过程中，有可能在导热材料板的导热材料板的下表面形成结露，容易引起结露聚集而滴落到室内影响卫生的问题；因此，导热材料板的下表面上还可以进一步的敷设亲水材料层或者防结露涂料层；借助亲水材料层可以对结露形成吸附，使结露不易滴落而被吸附在亲水材料层上挥发，从而防止结露聚集滴落而造成的卫生污染问题；但是对于我国南方等气候较为潮湿的地区，在导热材料板的下表面上采用亲水材料层可能回因其长时间吸水湿润而导致发霉，所以在这些地区更适合在导热材料板的下表面上敷设防结露涂料层，防结露涂料层不仅可以对结露形成吸附而防止其聚集滴落，并且防结露涂料层自身并不会被结露所浸润，因此也不会导致发霉，使用效果更佳。 In specific applications, in the capillary network radiation heat exchange ceiling plate of the present invention, the capillary heat exchange tubes can be straight tubes or U-shaped tubes. When the capillary heat exchange tubes are straight tubes, as shown in FIG. The water diversion tubes 107 are respectively located on both sides of the capillary heat exchange tubes, and are vertically arranged with the capillary heat exchange tubes 102. The meanings of other symbols in FIG. 5 are the same as those in FIGS. 1-4; Using U-shaped tubes, as shown in Figure 1, the two straight extensions on both sides of the U-shaped bend of the capillary heat exchange tubes are preferably parallel to each other, and the capillary heat exchange tubes on the heat-conducting material plate are preferably arranged in a straight line. The extensions are arranged in parallel with each other to form a line of capillary heat exchange tubes. The water supply diversion pipe and the return water diversion tube are located on the same side of the capillary heat exchange tube lineup, and are adjacent to the straight extension of each capillary heat exchange tube. vertical set. Such an arrangement of capillary heat exchange tubes, water supply diversion tubes and return water diversion tubes can make use of the interior space of the ceiling panel shell as much as possible, so that the capillary heat exchange tubes are arranged on the heat-conducting material plate to form a smaller coverage area. The heat transfer coverage area is large and the heat transfer effect of each area is relatively balanced. The heat exchange medium used in the capillary network radiative heat exchange ceiling panel of the present invention may be the heat exchange medium commonly used in the prior art radiant ceiling panel technology, such as water, refrigerant and the like. And the concrete material of capillary heat conduction tube and heat conduction material plate, can adopt the manufacturing material of capillary heat conduction tube and heat conduction material plate in existing radiant ceiling board, and as preferably, when using water as heat exchange medium, capillary heat conduction tube preferably adopts Polyethylene plastic tubes, which can meet the heat transfer performance requirements, help to reduce costs; when using refrigerant as the heat transfer medium, the capillary heat transfer tube is best to use copper tubes to ensure that the capillary heat transfer tube has excellent performance. Thermal conductivity and corrosion resistance. The material of the thermally conductive material plate is preferably galvanized steel sheet, so that it can not only have relatively good thermal conductivity and anti-corrosion performance, but also can take into account the aesthetics at the same time. In addition, since the heat-conducting material plate is used as the bottom panel of the ceiling plate shell in the capillary network radiation heat exchange ceiling plate of the present invention, it is considered that during the cooling process in summer, it is possible that the lower surface of the heat-conducting material plate of the heat-conducting material plate Condensation is formed, which is easy to cause condensation to gather and drip into the room to affect hygiene; therefore, a layer of hydrophilic material or an anti-condensation coating layer can be further laid on the lower surface of the thermally conductive material plate; with the help of the layer of hydrophilic material, it can It can form adsorption to condensation, so that condensation is not easy to drip and is adsorbed and volatilized on the hydrophilic material layer, thereby preventing sanitary pollution caused by condensation accumulation and dripping; The use of a hydrophilic material layer on the lower surface of the material board may cause mildew due to its long-term water absorption and moisture, so it is more suitable to lay an anti-condensation coating layer on the lower surface of the heat-conducting material board in these areas. The anti-condensation coating layer is not only It can absorb condensation to prevent it from gathering and dripping, and the anti-condensation coating layer itself will not be soaked by condensation, so it will not cause mold and mildew, and the use effect is better.
此外，值得注意的是，本发明的毛细管网辐射换热吊顶板采用了模块化的设计，可以采用多块毛细管网辐射换热吊顶板在室内屋顶上进行铺装，并且由于毛细管网辐射换热吊顶板上吊顶板壳体同侧的侧面板或两个相对的侧面板上设置了用于连接供水管道的供水接口和用于连接回水管道的回水接口，从而可以通过布设供水管道和回水管道分别与毛细管网辐射换热吊顶板的供水接口和回水接口相连通形成换热介质流动回路；同时，本发明的毛细管网辐射换热吊顶板在相邻于供水接口（或回水接口）所在侧面板的两个相对的侧面板上的对应位置处还设置有连接结构，且这两个相对侧面板上的连接结构能够相互匹配连接，这样以来，如图6所示，就可以使需要布设的多个毛细管网辐射换热吊顶板10之中，每相邻两个毛细管网辐射换热吊顶板10之间可以通过各自的连接结构相互连接在一起，从而排列形成一个吊顶板列队，这样更便于铺设安装；并且，由于毛细管网辐射换热吊顶板10的吊顶板壳体上的连接结构所在侧面板与供水接口（或回水接口）所在侧面板之间是相邻的侧面板位置关系，因此多个毛细管网辐射换热吊顶板10通过各自的连接结构相互连接形成吊顶板列队之后，恰好使得各个毛细管网辐射换热吊顶板的供水接口和回水接口分布于吊顶板列队的同侧（在供水接口和回水接口设计于毛细管网辐射换热吊顶板的同侧的情况下）或两侧（在供水接口和回水接口设计于毛细管网辐射换热吊顶板的两侧的情况下），图6就示出了供水接口和回水接口分布于吊顶板列队两侧的情况，这样以来，就可以在吊顶板列队的两侧分别布设供水管道20和回水管道30，分别与各个毛细管网辐射换热吊顶板10的供水接口和回水接口相互连通。具体而言，本发明的毛细管网辐射换热吊顶板用于吊顶铺装的具体铺装结构如下：采用若干个本发明的毛细管网辐射换热吊顶板，排列形成至少一个吊顶板列队，安装在室内屋顶上；每一个吊顶板列队由多个毛细管网辐射换热吊顶板单列排列而形成，其中每相邻两个毛细管网辐射换热吊顶板之间通过各自吊顶板壳体侧面板上的连接结构相连接，且同一个吊顶板列队中，各个毛细管网辐射换热吊顶板的供水接口所在侧面板均朝向同一侧，各个毛细管网辐射换热吊顶板的回水接口所在侧面板均朝向同一侧；每一个吊顶板列队的各毛细管网辐射换热吊顶板供水接口所在一侧布设有供水管道且分别与各供水接口相连通，每一个吊顶板列队的各毛细管网辐射换热吊顶板回水接口所在一侧布设有回水管道且分别与各回水接口相连通。本发明毛细管网辐射换热吊顶板的吊顶铺装结构，根据毛细管网辐射换热吊顶板中毛细换热管的不同排列布局，以及供水接口和回水接口位于同侧或异侧的不同情况，其具体的铺装表现形式也有所不同；例如，图6示出了采用多个毛细管网辐射换热吊顶板10铺设单个吊顶板列队，在吊顶板列队两侧分别布设供水管道20和回水管道30的情况；图7示出了采用多个毛细管网辐射换热吊顶板10铺设为两个并列的吊顶板列队，在两个并列吊顶板列队的两侧分别布设供水管道20和回水管道30的情况；图8示出了采用多个毛细管网辐射换热吊顶板10铺设为两个相间隔的吊顶板列队，在两个吊顶板列队之间布设供水管道20和回水管道30的情况；当然，还可以采用很多其他的铺装布设方式。除此之外，为了更便于对该吊顶铺装结构中各个毛细管网辐射换热吊顶板的开关控制以及维修、更换，如图6、图7、图8所示，在供水管道20分别与各供水接口相连通的连通接头位置处或者回水管道30分别与各回水接口相连通的连通接头位置处，还可以增加设置电控流量阀40，通过电控流量阀40分别调整和控制每一个毛细管网辐射换热吊顶板10中毛细换热管的换热介质流通量，达到调节换热能力或关停部分吊顶板的作用。 In addition, it is worth noting that the capillary network radiation heat exchange ceiling panel of the present invention adopts a modular design, and multiple capillary network radiation heat exchange ceiling panels can be used to pave the indoor roof, and due to the capillary network radiation heat exchange The side panel on the same side of the ceiling panel shell on the ceiling plate or two opposite side panels are provided with a water supply interface for connecting the water supply pipe and a return water interface for connecting the return water pipe, so that the water supply pipe and the return water pipe can be laid out. The water pipes are respectively connected with the water supply interface and the return water interface of the capillary network radiation heat exchange ceiling plate to form a heat exchange medium flow circuit; at the same time, the capillary network radiation heat exchange ceiling plate of the present invention is adjacent to the water supply interface (or return water interface) ) is also provided with connection structures at the corresponding positions on the two opposite side panels of the side panel, and the connection structures on the two opposite side panels can be matched and connected with each other, so that, as shown in Figure 6, the Among the multiple capillary network radiation heat exchange ceiling panels 10 that need to be laid out, every two adjacent capillary network radiation heat exchange ceiling panels 10 can be connected to each other through their respective connection structures, thereby forming a ceiling panel row. This is more convenient for laying and installation; and, since the side panel where the connection structure on the ceiling panel shell of the capillary network radiation heat exchange ceiling panel 10 is located and the side panel where the water supply interface (or return water interface) is located is the adjacent side panel position Therefore, after multiple capillary network radiation heat exchange ceiling panels 10 are connected to each other through their respective connection structures to form a ceiling panel lineup, the water supply interface and return water interface of each capillary network radiation heat exchange ceiling panel are distributed at the same time as the ceiling panel lineup. Side (when the water supply interface and return water interface are designed on the same side of the capillary network radiation heat exchange ceiling plate) or both sides (in the case where the water supply interface and return water interface are designed on both sides of the capillary network radiation heat exchange ceiling plate) Bottom), Figure 6 shows the situation that the water supply interface and return water interface are distributed on both sides of the ceiling slab lineup, so that the water supply pipeline 20 and the return water pipeline 30 can be respectively arranged on both sides of the ceiling slab lineup, respectively The water supply interface and the water return interface of each capillary network radiation heat exchange ceiling plate 10 are connected to each other. Specifically, the specific pavement structure of the capillary network radiation heat exchange ceiling tiles of the present invention used for ceiling pavement is as follows: several capillary pipe network radiation heat exchange ceiling tiles of the present invention are arranged to form at least one ceiling tile lineup, and installed on On the indoor roof; each ceiling board lineup is formed by a single row of multiple capillary network radiation heat exchange ceiling boards, wherein every two adjacent capillary network radiation heat exchange ceiling boards are connected through the side panels of the respective ceiling board shells The structures are connected, and in the same ceiling slab lineup, the side panels where the water supply interfaces of each capillary network radiative heat exchange ceiling slab are located face the same side, and the side panels where the water return interfaces of each capillary network radiant heat exchange ceiling slab are located are all oriented to the same side ; Each capillary network radiative heat exchange ceiling slab water supply interface of each ceiling slab is arranged on the side where the water supply pipe is arranged and is connected with each water supply interface respectively, and each capillary network radiative heat exchange ceiling slab return water interface of each ceiling slab is arranged A return water pipe is arranged on the side where it is located and communicates with each return water interface respectively. The ceiling pavement structure of the capillary network radiation heat exchange ceiling plate of the present invention is based on the different arrangements and layouts of the capillary heat exchange tubes in the capillary network radiation heat exchange ceiling plate, and the different situations that the water supply interface and the return water interface are located on the same side or different sides, The specific pavement manifestations are also different; for example, Fig. 6 shows that multiple capillary network radiation heat exchange ceiling panels 10 are used to lay a single ceiling panel lineup, and water supply pipes 20 and return water pipes are respectively arranged on both sides of the ceiling plate lineup 30 situation; Fig. 7 has shown adopting a plurality of capillary network radiation heat exchange ceiling slabs 10 to be laid as two side by side ceiling slabs lined up, the water supply pipeline 20 and return water pipeline 30 are respectively laid out on both sides of two parallel ceiling slabs lined up Figure 8 shows the use of a plurality of capillary network radiative heat exchange ceiling panels 10 laid as two spaced apart ceiling panels line up, between the layout of the two ceiling panels lined up the situation of water supply pipeline 20 and return water pipeline 30; Of course, many other pavement layout methods can also be used. In addition, in order to facilitate the switch control, maintenance and replacement of each capillary network radiation heat exchange ceiling board in the suspended ceiling pavement structure, as shown in Figure 6, Figure 7 and Figure 8, the water supply pipe 20 is connected to each At the connection joint position where the water supply interface is connected or at the connection joint position where the return water pipe 30 is respectively connected with each return water interface, an electronically controlled flow valve 40 can also be added to adjust and control each capillary through the electronically controlled flow valve 40.

In Fig. 11 and Fig. 12, the relatively left temperature distribution diagram shows the temperature distribution of the capillary network radiation heat exchange ceiling panel of the present invention, and the relatively right temperature distribution diagram shows the temperature distribution of the prior art radiant ceiling panel. From the temperature distribution shown in Figure 11 and Figure 12, under the same parameter settings and ambient temperature conditions, no matter in the edge vertical section area or in the middle vertical section area, the capillary network radiation conversion of the present invention The indoor temperature and low temperature area around the thermal ceiling board is more than that of the prior art radiant ceiling board, and the indoor temperature field formed by the capillary network radiation heat exchange ceiling board of the present invention is also more uniform than the prior art radiant ceiling board, and the temperature difference is smaller. It can be seen that the cooling performance of the capillary network radiation heat exchange ceiling panel of the present invention is also better than that of the prior art radiation ceiling panel in summer.
综上所述，可以看到，本发明毛细管网辐射换热吊顶板通过结构的改进，其导热材料板上与毛细导热管相接触位置处形成向下凹陷且与毛细导热管的下侧管壁形状相匹配的沟槽，使得毛细导热管的下侧管壁陷入所述沟槽中且与沟槽的槽壁相贴合接触，大幅增加了毛细导热管与导热材料板之间的直接接触传热面积，减少了二者之间热传导过程中热量/冷量的消耗，增强了毛细导热管与导热材料板之间的导热效率，同时增加了导热材料板下表面的换热接触面积，使得导热材料板也具备了更好的对外换热效果，加上相对封闭的吊顶板壳体结合反射膜的采用以及保温隔热材料的填充所起到的反射、隔热及向下挤压作用，使得毛细换热管向外传导的热量/冷量被尽可能的向下传递给导热材料板，减少换热能量散失，提高换热能量利用率，从而进一步的提升本发明毛细管网辐射换热吊顶板的换热能效，提升了本发明毛细管网辐射换热吊顶板的供暖、供冷能力，且抑制供暖、供冷能力增强后所带来的技术弊端，能够很好的解决现有技术中辐射吊顶板技术中供暖、供冷能力受限而限制其技术应用推广的问题；并且，本发明的毛细管网辐射换热吊顶板采用了模块化的结构，可以直接用于吊顶铺装形成多种形式的吊顶铺装结构，安装方便，且排布形式灵活多样，可以应用于不同的建筑场景中，具有广阔的市场应用前景。 In summary, it can be seen that through the improvement of the structure of the capillary network radiation heat exchange ceiling plate of the present invention, a downward depression is formed at the position where the heat-conducting material plate is in contact with the capillary heat-conducting tube and is connected to the lower side wall of the capillary heat-conducting tube. The groove with matching shape makes the lower tube wall of the capillary heat pipe fall into the groove and is in contact with the groove wall of the groove, which greatly increases the direct contact between the capillary heat pipe and the heat conduction material plate. The thermal area reduces the consumption of heat/cold during the heat conduction process between the two, enhances the heat conduction efficiency between the capillary heat pipe and the heat conduction material plate, and increases the heat exchange contact area on the lower surface of the heat conduction material plate, making the heat conduction The material board also has a better external heat exchange effect, and the reflection, heat insulation and downward extrusion effect of the relatively closed ceiling board shell combined with the adoption of reflective film and the filling of thermal insulation materials make the The heat/cooling capacity conducted outward by the capillary heat exchange tube is transferred downwards to the heat-conducting material plate as much as possible, reducing the loss of heat exchange energy and improving the utilization rate of heat exchange energy, thereby further improving the capillary network radiation heat exchange ceiling panel of the present invention The heat exchange energy efficiency improves the heating and cooling capacity of the capillary network radiation heat exchange ceiling panel of the present invention, and suppresses the technical disadvantages caused by the enhanced heating and cooling capacity, which can well solve the radiation ceiling in the prior art The heating and cooling capacity of the panel technology is limited, which limits its technical application and popularization; moreover, the capillary network radiation heat exchange ceiling panel of the present invention adopts a modular structure, which can be directly used for ceiling paving to form various forms of The suspended ceiling pavement structure is easy to install, and the arrangement forms are flexible and diverse. It can be applied in different architectural scenarios and has broad market application prospects.
